Debug Port on A1278 Late 2011 13.3 EMC 2555

[Deadoc3]

Where is in this model debug port?

Or i have to use clamp?

[Deadoc3]

Solved with clamp and MacBook now start correctly:

(+) Speed selector is active now, High Speed, Medium Speed, Slow Speed, and eXtra Slow Speed available, for the rare cases when the mac give malformed IDs when using Detect SPI at the default high speed,
(+) Writing Notice added, it will displayed when user either use write full, or write sync options,
(*) Finalized Reverse Algorithm for Full Write method,it will start from the end of the image and go towards begin, this will prevent SMC trying to boot machine to earlier is used in system programing,
(*) Fixed Write Sync method issue which caused write to fail when the chip was mounted on the SOIC8 clam,
(+) Minor Fine tunnings & tweaks.

HI.
Where? Can you upload a photo indicating the position?This will help other users. I do not have logicboard of this model now.

Thank

Sure. The chip is marked in this photo

Obviously, not need to disassembly logic board. With battery charged and attached, only connect clamp, with red wire on first chip pin, and do jobs with HD-Box.

yes is it.
thank you four your share.
